4.0 Flowmaster?

I have a Flowmaster 40 series laying in the basement. 2.5 in/out.
Was going to throw it on the 5.9l in my Durango but it is dead so was thinking about throwing it on the 03 Cherokee.
I know it at make me any hp or friends in the neighborhood lol but has anyone here done it? Will I lose hp or "performance"?
Or any other issues that could arise?

It do get a tad more noisy with a Flowmaster--even one designed for the 4.0.

But, it is making more POWER, because any kid with cards in their spokes knows noise=power.
